Remove Docker references from documentation and code

[BOHEUS]

As core team decided not to support Docker development containers here thanks to many tickets in #help channel on Discord server and general problems in maintaining, we should clean this before next release. Only Docker dev containers should be affected, Postgres and Redis container are still supported.

Tasks

Preview Give feedback

1. Remove Dockerfiles for Docker from packages/twenty-docker
2. Remove Docker references in developers' documentation (twenty-website/src/content/developers)

@charlesBochet did I miss something? If you want, I can handle this

[charlesBochet]

@BOHEUS I think we should keep them but make clear they are community maintained.
I think we can get rid of:

• twenty-docker/twenty-website
• Makefile

but I would keep the other ones.

Regarding the docs, we should remove the references to docker except for self-hosting + postgres local container. I'm not sure there are actually

[charlesBochet]

I think the mindset of these dockers config is that they can be used for production hosting (production built container). We don't want to support docker for local setup (to contribute).

So the Makefile does not make sense + twenty-website does not makes sense

• twenty is still useful for self-host
• postgres + postgres-spilo are useful to get postgres for self-host (and local contribution for this one as we don't need a dev specific container for postgres)

[BOHEUS]

Okay, I'll handle this and create a PR soon

TY!
